ath6kl: cleanup ath6kl_reset_device()

Move it to init.c, make it static, remove all useless checks and force it to
always do cold reset.

ath6kl: Fix missing gpio pin 9 configuration

GPIO pin 9 also needs to be configured along with other gpio
pins to avoid sdio crc errors. I've not experienced any issue
with missing this particular gpio pin configuration, found dunring
code review. This can potentially improve rx performance.

ath6kl: add board address to struct ath6kl_hw

This is to make it configurable by firmware IEs. Also determine if we need
to write or read the board address to the chip by checking if board address
is set or not.

ath6kl: remove hw version related parameter defines

Having separate defines, in a different file, makes it difficult to read
the actual values. As we are just setting named fields in a struct
the defines don't make any sense anymore.

There are no functional changes, only moving of constants.

ath6kl: read firmware start address from hardware

It's actually possible to read the firmware start address from hardware,
that way there's no need to hardcode the address in hardware.

Thanks to Chilam Ng for the idea.

ath6kl: Allow enabling of P2P support

For now, use a module parameter (ath6kl_p2p) to allow P2P support
to be enabled. This is needed since there is no mechanism for
enabling the P2P mode more dynamically for a single netdev.

ath6kl: read fwlog from firmware ring buffer

Firmare sends the logs only when it's internal ring buffer is full. But
if firmware crashes we need to retrieve the latest logs through diagnose
window. This is now done everytime the debugfs file is read.

ath6kl: add firmware log support

Firmware sends binary logs with WMIX_DBGLOG_EVENTID event. Create
a buffer which stores the latest logs and which can be copied from
fwlog debugfs file with cp command.

To save memory firmware log support is enabled only when CONFIG_ATH6KL_DEBUG
is enabled.

Add ath6kl cleaned up driver

Last May we started working on cleaning up ath6kl driver which is
currently in staging. The work has happened in a separate
ath6kl-cleanup tree:

http://git.kernel.org/?p=linux/kernel/git/kvalo/ath6kl-cleanup.git;a=summary

After over 1100 (!) patches we have now reached a state where I would
like to start discussing about pushing the driver to the wireless
trees and replacing the staging driver.

The driver is now a lot smaller and looks like a proper Linux driver.
The size of the driver (measured with simple wc -l) dropped from 49
kLOC to 18 kLOC and the number of the .c and .h files dropped from 107
to 22. Most importantly the number of subdirectories reduced from 26
to zero :)

There are two remaining checkpatch warnings in the driver which we
decided to omit for now:

drivers/net/wireless/ath/ath6kl/debug.c:31:
WARNING: printk() should include KERN_ facility level
drivers/net/wireless/ath/ath6kl/sdio.c:527:
WARNING: msleep < 20ms can sleep for up to 20ms;
see Documentation/timers/timers-howto.txt

The driver has endian annotations for all the hardware specific
structures and there are no sparse errors. Unfortunately I don't have
any big endian hardware to test that right now.

We have been testing the driver both on x86 and arm platforms. The
code is also compiled with sparc and parisc cross compilers.

Notable missing features compared to the current staging driver are:

o HCI over SDIO support
o nl80211 testmode
o firmware logging
o suspend support

Testmode, firmware logging and suspend support will be added soon. HCI
over SDIO support will be more difficult as the HCI driver needs to
share code with the wifi driver. This is something we need to research
more.

Also I want to point out the changes I did for signed endian support.
As I wasn't able to find any support for signed endian annotations I
decided to follow what NTFS has done and added my own. Grep for sle16
and sle32, especially from wmi.h.

Various people have been working on the cleanup, the hall of
fame based on number of patches is:
